             Summary: Fix schema handling in v1 and v2 drivers
                 Key: IGNITE-5319
                 URL: https://issues.apache.org/jira/browse/IGNITE-5319
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
             Fix For: 2.1


Currently both drivers behave as follows: when schema is changed, it is converted to cache name automatically. This is wrong. We should do the following:
1) Decouple schema name from cache name. Schema name should be separate field. No conversion.
2) When JDBC driver is connected, schema is set to the schema target cache belongs to
3) Cache name cannot be changed
4) Cache name is always passed to all tasks as before
5) Schema name is added to these tasks and propagated to respective {{SqlFieldsRequest}}. 
6) When done, {{H2Schema.cacheName}} and all it's usages could finally be removed.
